﻿8 BOTANICAL NOTES FROM NORTH CARDIGANSHIRE . 



* Calamintha officinalis Moencb. Frequent. 

 Scutellaria minor L. Penuwch. 



\Galeopsis speciosa Mill. Ty Newydd, Devil's Bridge; under 

 Pen-y-Banau. 



*Littorella lacustris L. Llyn Ieuan; Llantrissant ; Pond-yr- 

 oerfa ; Llyn Teifi ; Llyn Hir ; Llyn Egnant ; Llyn Fach ; Llyn-y- 

 Gorlan; Llyn Crugnant ; Llyn Berwyn ; Llyn Eiddwen ; Llyn Fanod. 



t A triplex patula L. Tregaron ; Pont-rliyd-fendigaed. 



t Polygonum Convolvulus L. Ty Cam. 



t FAiphorbia Helioscopia L. Yspytty Cynfyn ; Henffordd Arms ; 

 Llanfihangel Lledrod. 



TJrtica dioica L. A septal plant up to 800-900 ft. ; beyond this 

 it is dependent on man ; our highest records are for places where 

 man has disturbed the ground, i. e., under walls of ruined cottage8 

 or sheep-folds. Highest record, Hengae, 1350 ft.— U. turns L. Hen 

 Hafod (1170 ft.), on a manure-heap; seen nowhere else in the hills. 



*Betula alba L. Bwlch-nant-yr-Arian ; Gors-goch-lan-Teifi ; 

 certainly not planted in these places. Branches of this plant may 

 be seen in the peat bogs at greater heights than these, testifying 

 how it has existed over wide stretches of country. BlyttJ has 

 shown how the remains of generations of forests overlie one another 

 in the peat bogs of Norway, leaf trees below Coniferae, tracing this 

 as due to alternating wet and dry periods. A similar change must 

 have happened to destroy the birch trees in Cardigan, and cause 

 them to be buried in layer after layer of Sphagnum and other peat 



Salix aurita L. Frequent, becoming a dwarf plant under 3 ft. 

 high in the following upland situations :— Top of Pen-y-Banau 

 (1150 ft.); Llyn Teifi (1410 ft.); under Pen Drosgol (1060ft.); 

 Bwlch-nant-yr-Arian (1020 ft.). The catkins were bursting under 

 Pen Drosgol on Sept. 6th, 1893.

 Ddu (1660 ft.) ; Cefn Blaen Myherin (1440 ft.).
